How to shutdown 3PAR 7200 for maintaince?

[HoaNV9]

Dear HP,

Could you please to guide me how to shut down 3PAR SAN for maintaince plan. Please reivew the scenario as below:

In case of power outage, the UPS can not handle for long time we need to shutdown all the SAN System:

- With SAN Switch, we can do turn of by the power button.

- With SAN controller, how to shutdown to make sure that all the data be in protected.

Thank you.

I see two questions.

For maintenance, see the HP 3PAR StoreServ 7000 Storage Troubleshooting Guide, chapter 3, for instructions on powering down and back up.

For power outage, the controller nodes' cache memory is written to the nodes' on-board disk. The process is reversed when power comes back on, then the controllers finish any IOs that were in flight at the time of the power outage to the physical disks.

Note: While I work for HP, all of my comments (whether noted or not), are my own and are not any official representation of the company.

I was just discussing this yesterday.

The consensus was you can't.  If you have to turn off the power to service, you're usually right there.

There is no iLO nor a connection from the SP to do that.

Hi Flera,

Agree with Dennis that these can't be powered on remotely. But 3PAR StoreServ boots automatically upon power restore. So if you are able to switch off and switch on circuits on UPS (assuming that these are smart UPS with remote management module), 3PAR nodes will start booting after power restore.

Hope that helps.

Why on earth would you reference another document (and not link to it, I might add) instead of just posting the answer?!

Official documents are always good to mention.

There were two pages there, with Notes and Cautions and with fancy formatting.
